Method: spaces.messages.update

Updates a message. There's a difference between the patch and update methods. The patch method uses a patch request while the update method uses a put request. We recommend using the patch method. For an example, see Update a message.

Requires authentication. Supports app authentication and user authentication. When using app authentication, requests can only update messages created by the calling Chat app.

HTTP request


The URL uses gRPC Transcoding syntax.

Path parameters



Resource name of the message.

Format: spaces/{space}/messages/{message}

Where {space} is the ID of the space where the message is posted and {message} is a system-assigned ID for the message. For example, spaces/AAAAAAAAAAA/messages/BBBBBBBBBBB.BBBBBBBBBBB.

If you set a custom ID when you create a message, you can use this ID to specify the message in a request by replacing {message} with the value from the clientAssignedMessageId field. For example, spaces/AAAAAAAAAAA/messages/client-custom-name. For details, see Name a message.
